🧪 Formulation Notes

NOW Grape Seed Extract is a highly concentrated extract with a minimum of 90% polyphenols, including oligomeric proanthocyanidins (OPCs), which are the potent water-soluble free radical scavenging compounds found in grape seeds.

A growing body of research indicates that grape seed OPCs may help to support the health of vascular, bone, kidney, brain and other tissues by supporting a healthy, balanced immune response to oxidative and metabolic stress.

Natural color variation may occur in this product.
